This experiment was carried out to distinguish between picea abies (L.) Karsten and Picea koraiensis Nak by the method of discriminant analysis which is used the metrical continuous characteristic on current inorphological plant taxanomy. The results are summarized as follows 1) The discriminant function and discriminant region from the experiment are Z(x)=Z(x₁,x₂)=0.000379x₁+0.004354x₂-0.311061or Z(x)=Z(x₁,x₂)=0.000379(x₁-60.442800)+0.004354(x₂-66.185100)R₁=(x│0.000379x₁+0.004354x₂-0.311061≥0), R₂=(x│ 0.000379x₂+0.004354x₂-0.311061＜0). 2) The probability of misclassification based on the above discriminant region is P(2│1)=(P1│2)=0.444 therefore the probability of simultaneous misclassification of P(2│1) and P(1│2) is about 44.4%. 3) the probability of misclassification by the discriminant function resulted from the experiment if recorded as high but it is thought that there is a considerable meaning to perceive the probability of confidence about the discrimination better than its precision
